Cannot "Baking the Wiggle" in Blender v2.92.0
Disabling &quot;Additive Bake&quot; solved my problem!
I think there was a problem with the add-on, or the &quot;compatibility&quot; of the NLA. (?)

When you do an additive bake, it pushes your animation into an NLA strip and bakes the wiggle into the active action. — blenderartists.org

? = I don't know how blender's add-ons system is working, but reopening the editor or reload the same file can also solve the problem. (maybe a corrupted code sequence in the add-on)
